Please help me afford treatment for my poor kitten

My kitten was neutered last week and after his surgery he was very lethargic. His sister was spade at the same time, even though her surgery was more serious she was fine. I took Dumbledore to the vet but they could not tell me why he was running a fever and had swollen glands. I had him put on antibiotics thinking it was an infection, at this point vet visits had cost about $700.00. The antibiotics did not seem to cause any improvement, and since he wasn't drinking I had to use a syringe (no needle) to put water in his mouth so he would drink. Back to the vet with them both (she doesn't like to be without him and vice versa) and another $200.00 later we still did not know what was wrong, and I was told to monitor him. 2 visits later and another $300, and now my girlfriend and I are recommended to take him to a specialist, at this point I'm very frustrated and feel terrible for Dumbledore as he has had many shots and had his temperature taken many times, poor guy. But finally we take him to the specialist, they take blood and do an x Ray, which we are waiting on results for, they think it maybe FIP. But this visit put my total well over $1,400.00. So I am making this hooping people will find it in their hearts to donate a couple dollars, thank you all for your help and consideration, anything helps when you're struggling! Hopefully our results will be good, but if not your donations will go to helping him further.
